No clear documentation on how to setup an efficient development environment and reload an add-on during development, leading to slow and frustrating experiences by newer add-on developers.
Imagine being a new add-on developer who just finished the Add-on Tutorial (https://docs.blender.org/manual/en/dev/advanced/scripting/addon_tutorial.html#intended-audience). You wrote a .py file and wonder, do I really need to add every .py file through `Preferences ‣ Add-ons ‣ Install…`?
- Please mention that you can set a default script location with: `Edit ‣ Preferences ‣ File Paths ‣ Data ‣ Scripts`.
Next, we realize you rather write "create blocks" as "Create Blockies", but wait, or add-on is already loaded. How do I reload the add-on? Do I really have to close Blender every time? With your Google skills (https://blender.stackexchange.com/questions/2691/is-there-a-way-to-restart-a-modified-addon) you find that F8 should reload all add-ons... except it doesn't, because that's for 2.79. Luckily you read through the comments and realize you have to go through the painful process of searching for `F3 -> reload scripts -> enter` every time we need to reload a change. In the other answer you find `bpy.ops.wm.addon_enable(module='your_module_name')` for in the Blender terminal, which might be slightly faster (just arrow-up -> enter). You continue for a while and started to make a multi-file add-on. Suddenly your code shortcut doesn't reload every change you make? After some experimenting you find out that only changes in `__init__.py` are noticed, so you go to (https://blender.chat/channel/python) and ask what is wrong (https://blender.chat/channel/python?msg=fGEyJtjNZqfpApxQ5). Which doesn't solve your issue, so you dive in the code of ``bpy.ops.wm.addon_enable()` and make an issue about it (https://developer.blender.org/T66924). There, someone points out that actually `bpy.ops.script.reload()` is the right code command, not `bpy.ops.wm.addon_enable(module='your_module_name')`
- Please mention that you can reload ALL add-ons with `F3 -> reload scripts -> enter` or the correct code line `bpy.ops.script.reload()`.
You hear you can set a keyboard shortcut for reload, so you find an image about it (https://devtalk.blender.org/t/reload-button-in-2-8/1708). The image there doesn't tell you how to set the keyboard shortcut and `Preferences -> Keymap -> Search -> "reload script"` doesn't show up anything. So you Google now: "Blender 2.8 how to add a new shortcut", which shows only "Blender 2.8 changed these shortcuts!", so you add "your own", only to find this page saying it has not been implemented yet (https://blender.stackexchange.com/questions/124475/blender-2-8-how-to-add-a-new-shortcut). Then in a 2.79 YouTube video you find you first have to collapse a line (e.g. `Screen -> Global` where a button `Add New` shows up.
- Please include in the docs how to set a keyboard shortcut for add-on reloading: `Preferences -> Keymap -> Screen -> Screen (Global) -> Add New -> collapse -> see image`.
- Please also include (a link to) how to setup an IDE to develop your add-ons with.
By reading this, you might have noticed that getting into efficient Blender add-on development is quite frustrating with the current documentation. Please make an extra page about how to setup you add-on development environment, using the bullet points above, here: https://docs.blender.org/manual/en/dev/advanced/scripting/addon_tutorial.html#intended-audience
